BIM-ENABLED APPROACH FOR COMPUTATION OF CONSTRUCTABILITY SCORE

Abstract

Immediate perception to the construction landscape has continually been marred with the chronic issue of Construction Productivity for many countries including Singapore. This inadvertently manifests as detriments to project success in metrics of undesired cost, quality, time, and safety. As the City-state is constantly looking to improve its standing amongst others, a paradigm shift is indefinitely required. The deliberation of constructability issues during design phase can ergo effect improved construction performance apt with greater degree of project delivery success. Despite being reviewed as an effective scheme, the implementation of the Constructability (and buildability) scores are still not optimised for harnessing constructability improvement to date. Hence, the research study established an impetus to analysis the current system and emerging challenges. Otherwise, the approach will only be an untapped potential with the lack of implementation in the field. The proliferation of BIM technologies is viewed to facilitate construction processes in utilizing through an information-intensive and knowledge-driven approach. The effective implementation with current assessment tools presents itself as a potential decision support tool that can effect informed design decisions early in the project life-cycle. Factoring constructability from the outset into design solutions is highly favorable to bring about increased construction productivity. Thereupon, this study assesses how a model-based approach can be employed to integrate the design process with distinct constructability values. Subsequently, a “CASe” template system is proposed. As such, the effective use, the integration engendered by “CASe” may assumes a position of cardinal significance
